Not sure what to think of the video to be honest, but some questions about Krav (I know nothing of Krav Maga).

What kind of strikes are taught, and what kind of grappling techniques are taught (is it similar to Muay Thai and BJJ)? Also, in the video it *shows* (it might not even be Krav) two guys sparring with helmets on. My instructor teaches Muay Thai (I start next week), and he spars in the gym with pads on his legs and MMA gloves, but he definitely doesn't wear a helmet.

the guys in helmets are from straight blast gym, which is all about what matt thornton calls "aliveness" - so they try to make the scenarios and sparring as realistic as possible, i.e. trying to beat the •••• out of each other, which necessitates a lot of protective gear if you plan on doing it with any regularity.
